Embodiment 1

[0027] like figure 1 As shown, a processing method suitable for network video monitoring of DLP multi-screen splicing display wall, the method uses a built-in PC in each display unit, and the built-in PC performs single-picture and multi-picture signal processing on the remote IP camera signal Processing, the processing process includes the following steps:

[0028] Step 1, start the webcam;

[0029] Step 2, start the display unit of the built-in PC;

[0030] Step 3, the built-in PC in the display unit automatically starts the client;

[0031] Step 4, the display unit monitors and plays the camera signal;

[0032] Step 5, the built-in splicing processor of the DLP multi-screen splicing display wall completes the splicing of the images, and enlarges, shrinks, and moves the signals;

[0033] Step 6, the DLP multi-screen splicing display wall displays the processed signal;

[0034] Finally, repeat the above steps for multi-channel signal display.

[0035] The network camera...

Embodiment 2

[0039] like figure 2 As shown, a system structure diagram of a network video surveillance processing method suitable for a DLP multi-screen splicing display wall, the structure includes a DLP multi-screen splicing display wall 8, a switch 9, a centralized control terminal 10, and a network camera 11. The DLP multi-screen splicing display wall 8 has built-in embedded PC and splicing processor, and the switch is used to connect the centralized control terminal 10, the network camera 11, and the DLP multi-screen splicing display wall 8, and realize data communication between them . The invention combines a plurality of independent and scattered monitoring camera images into a super-large digital matrix through the network, and after centralized control, it is perfectly spliced ​​and displayed on the multi-screen splicing wall. Realize overall signal splicing, cross-screen, roaming, and switching display processing, and the display speed is fast, supporting 720 / 1080P high-defini...

Abstract

The invention relates to a processing method applicable to network video monitoring of a digital light processing (DLP) multi-screen splicing display wall. In the method, each display unit is provided with a built-in personal computer (PC) which performs single-image and multi-image signal processing on a remote-end IP camera signal, and the processing process comprises the following steps: a network camera is started; the display unit of the built-in PC is started; the built-in PC in the display unit automatically starts a client; the display unit monitors and plays the camera signal; a built-in splicing processor of the DLP multi-screen splicing display wall finishes image splicing and amplifies, minifies and moves the signal; the DLP multi-screen splicing display wall displays the processed signal; and multi-channel signals are displayed by repeating the steps. Compared with the prior art, the method of the invention has low cost, is simple in construction and can ensure infinite increase of the number of monitoring signal sources along with digital matrix functions, and the like.

Description

technical field [0001] The invention relates to a processing method for network video monitoring, in particular to a processing method for network video monitoring suitable for DLP multi-screen splicing display walls. Background technique [0002] In the display and control technology based on DLP multi-screen splicing, it is one of the important technologies to realize the monitoring and display of video signals on the multi-screen splicing wall. Video surveillance is a special and demanding technology in the application of multi-screen splicing display walls, which can realize the display of multiple surveillance camera signals on the large DLP splicing screen. In recent years, with the development of software and hardware technology, video signal monitoring has been widely used in centralized monitoring applications in roads, factories, safe cities, rail transit, public security, government and other fields. [0003] From the perspective of video signal processing in the...
